Preliminary findings of a study of sediment transport in streams with high concentrations of suspended fine sediment indicate that for Rio Puerco near Bernardo, New Mexico the velocity varies logarithmically with depth, and the concentration distribution for several size classes of sand may be described by a conventional distribution equation if the fall velocity of the sand is corrected for the influence of the fine sediment. A corrected fall velocity, empirically defined for a temperature of 24°C and for concentrations up to about 150,000 ppm, is given.

The purpose of this study was to investigate some aspects of the sediment transport parameters and the mechanics of flow in streams transporting high concentrations of suspended fine material. Field observations were conducted at a reach of the Rio Puerco near Bernardo, New Mexico. The data obtained were supplemented by existing records of the Rio Puerco and of other streams where applicable.
